CITY, STATE and NEAREST LARGE CITY are important because location may control code to be used for design. UV inhibitor is standard. UV coating may be specified for added protection. Many of our competitors do not have coating as an option. When bidding in a competitive situation, consider the extra cost.
Published load tables are available for DURADEK® and DURAGRID® gratings. The load tables specify span capabilities based on given load requirements. When quoting wheel loads (form lifts, hand carts, etc.) it is necessary to specify the wheel diameter and width along with the maximum load per wheel. Standard design load for pedestrian walkways is 100 PSF.
Standard colors are yellow and gray. Custom colors are available. Set-up charges for non-standard colors are determined by quantity/color. Polyester is the standard resin, except for 1-1/4" bearing bars and the DURAGRID® Economy series where it is vinyl ester. Non-standard runs are possible with a minimum order of 15,000 lineal feet, which in I-6000, is equivalent to approximately 1,875 ft2.
Standard sizes/colors available for a 2 - 5 day shipment are as follows: I-6000 1", I-6000 1-1/2" and T-5000 2" in yellow or gray polyester. Vinyl ester stock is sometimes maintained. All stock is inventoried in limited quantities and will only be held with a Purchase Order on a first come, first served basis.
A standard 316 S.S. saddle clip and a 316 S.S. insert clip are available. The saddle clip wraps around 2 bars and is recommended for stair tread applications. The insert hold down fits between the bars (this type "sandwiches" the bottom flange of the bar to the structural support member). Recommend 2 hold downs of each support with a minimum of 4 per panel.
Information to show or obtain: Plan view of grating layout for custom jobs and specification of grating type required. Custom panels may require detailed shop drawing submittals prior to order entry. Custom panels require longer lead times. If submittals are required it is necessary, to know the customer expected ship date, when drawings are required, number of sets required and the customer contact name/address the drawings for approval should be sent to. If a set of blueprints are not available from the customer, exact panel sizes will need to be specified.
